1. Given below are two statements: Statement-I: If a parallel paraxial beam of light were incident on a concave mirror, making some angle with the principal axis, the reflected rays would converge at a point in focal plane. Statement-II: Power(P) of concave mirror is positive even though focal length(f) is negative. In the light of the above statements, choose the most appropriate answer from the options given below.
2. Assertion (A): If an object moves in front of a concave mirror parallel to principal axis. The angle between the object velocity and image velocity can never be acute. Reason (R): Object velocity and image velocity perpendicular to principal axis for spherical mirror is not same.
3. A U-shaped wire is placed before a concave mirror having focal length 10 cm. Find the total length of the image :
4. In the figure shown find the total magnification after two successive reflections first on M1 & then on M2 (Take Ist reflection from concave mirror)
5. Assertion (A): In case of a concave mirror if a point object is moving towards the mirror along its principal axis then its image will always move away from the mirror. Reason (R): In case of reflection (along the principal axis of mirror) object and image always travel in same directions.
